[0022] Please refer to the following: A multi-station feeding and adjustable hopper size sheet material storage device. Figure 1-12 As shown, it includes: platform 100, hopper mechanism 200 and feeding mechanism 300, which can realize material storage and feeding.

[0023] Platform 100 is equipped with a storage area 101 and a processing area 102, such as Figure 1 and Figure 3As shown, the platform 100 has a base, which is generally made of metal and has high hardness. The upper surface of the base forms a storage area 101 and a processing area 102. The storage area 101 and the processing area 102 are arranged in the Y direction. The storage area 101 is mainly used to store the plates and plays a supporting role. For example, the processing area 102 is mainly used for processing the sheet metal after it is transferred to the processing area 102, by means of a drilling mechanism, a cutting mechanism, etc., or by means of an edge sealing mechanism, etc. The specific processing of the sheet metal in the processing area 102 is not specifically limited, and the specific structure and principle of the aforementioned drilling mechanism, cutting mechanism, etc. are not limited. The hopper mechanism 200 is installed on the platform 100 and located in the storage area 101. The hopper mechanism 200 includes: a set of symmetrically arranged slide rails 210, multiple hopper plates 220 installed on the slide rails 210, and support bars 230 installed on the hopper plates 220; wherein, every two hopper plates 220 constitute a hopper 201; as shown Figure 1 and Figure 6 As shown, the hopper mechanism 200 is equipped with 12 hopper plates 220, forming six hoppers 201, which can store six sets of plates; as Figure 9 As shown, when placing the board, it is placed from top to bottom into the space between the two hopper plates 220, and the board is discharged from the bottom. Generally, the hopper plate 220 is made of metal plate, which has the characteristic of high hardness.

[0024] The hopper plate 220 is mounted on the slide rail 210 via a locking slider 240 and moves along the slide rail 210 in the X direction to adjust the position of the hopper 201 in the storage area 101 and to adjust the width of the hopper 201. Here, the slider 240 adopts a locking slider structure, so that there are locked and unlocked states between the slider 240 and the slide rail 210; In the locked state, slider 240 can move along slide rail 210. If both hopper plates 220 of a hopper 201 move simultaneously along slide rail 210, the position of hopper 201 can be adjusted, such as... Figure 9 One of the hoppers 201 is moved to the left to adjust the position of the hopper 201 in the storage area 101; or, in the two hopper plates 220 of a hopper 201, only one hopper plate 220 is activated to open or close the distance between the two hopper plates 220, thereby adjusting the width of the hopper 201. After adjustment, lock slider 240 and slide rail 210, and the hopper 201 will be positioned.

[0025] In addition, such as Figure 6 As shown, the hopper mechanism 200 is equipped with six hoppers 201, and the width of each hopper 201 can be set to be different, so as to hold plates of different widths.

[0026] The slider 240 and slide rail 210 mentioned above can adopt existing technologies, such as the dual-axis linear guide locking structure of Chinese Publication No. CN217977045U; or the dual-axis linear guide of Chinese Publication No. CN220986365U. Both can achieve a locked state and an unlocked state between the slider 240 and the slide rail 210. The above two patented technologies are for reference only. In this embodiment, the slider 240 and slide rail 210 can adopt other existing technologies.

[0027] The support bar 230 includes a first support bar 231 and a second support bar 232; the first support bar 231 is fixedly installed on the front side of the hopper plate 220, and the second support bar 232 is movably installed on the rear side of the hopper plate 220. The second support bar 232 moves along the hopper plate 220 in the Y direction to adjust the length of the hopper 201; for plates of different lengths, the position of the second support bar 232 is selectively adjusted to adapt to plates of different lengths and meet the user's needs; like Figure 6 As shown, the hopper mechanism 200 is equipped with six hoppers 201. The length of each hopper 201 is adjusted to be different by the second support bar 232, so that it can hold plates of different lengths.

[0028] like Figure 8 and Figure 9 As shown, in a hopper 201, a first support bar 231 and a second support bar 232 are installed on the corresponding sides of two hopper plates 220, which are distributed in a four-corner arrangement. After the plate is put into the hopper 201, its front side abuts against the first support bar 231, its rear side abuts against the second support bar 232, and its left and right sides are restricted between the two hopper plates 220, thus achieving the limiting function.

[0029] The first support bar 231 and the second support bar 232 are preferably made of sheet metal, which has high hardness, simple structure and convenient installation.

[0030] Furthermore, the first support bar 231 and the second support bar 232 can be fixed to the hopper plate 220 with screws.

[0031] The feeding mechanism 300 is located at the bottom of the storage area 101, pushing the sheet material from the hopper 201 into the processing area 102; as Figure 1 As shown, the feeding mechanism 300 pushes the sheet material in the Y direction, moving it from the storage area 101 to the processing area 102; if... Figure 5 The orientation indicates that the feeding mechanism 300 pushes the board upward, moving it from the storage area 101 to the processing area 102.

[0032] Furthermore, such as Figure 6As shown, the hopper mechanism 200 also includes a support frame 260, which is in the shape of a frame. The slide rail 210 is fixedly installed on the support frame 260. The support frame 260 has stop bars 261 on both sides in the X direction, which serve to protect and limit movement.

[0033] In one embodiment, a strip groove 221 is formed on the hopper plate 220, and the strip groove 221 is formed along the Y direction, such as... Figure 8 As shown, there are two strip grooves 221, one at the high position and the other at the low position; the second support bar 232 is provided with a fixing nut 2321, and the screw part 251 of an adjusting handle 250 passes through the strip groove 221 and is connected to the fixing nut 2321. In silo 201, the corresponding sides of the two silo plates 220 are defined as the inner sides, and the opposite sides are defined as the outer sides, and so on. Figure 8 As shown, the first support bar 231 and the second support bar 232 are installed on the inner side of the hopper plate 220, and the adjusting handle 250 is located on the outer side. The screw part 251 of the adjusting handle 250 passes through the strip groove 221 and is connected to the fixing nut 2321. Rotating the adjusting handle 250 in the forward direction will fasten the second support bar 232 to the hopper plate 220. Specifically, when rotating the adjusting handle 250 in the forward direction, the screw part 251 will be screwed into the fixing nut 2321 to lock the second support bar 232 and the hopper plate 220. After the second support bar 232 is loosened by rotating the adjustment handle 250 in the reverse direction, it can move in the Y direction. Specifically, when the adjustment handle 250 is rotated in the reverse direction, the screw part 251 is screwed outward, but it does not completely disengage from the fixing nut 2321. The second support bar 232 and the hopper plate 220 are loosened, the screw part 251 moves along the strip groove 221, and the second support bar 232 moves in the Y direction. After it moves into place, the adjustment handle 250 is rotated in the forward direction again to lock the second support bar 232 and the hopper plate 220, thus completing the adjustment. The structure is simple and the adjustment is convenient.

[0034] In one embodiment, a limiting support bar 233 is provided at the lower end of the first support bar 231; an elongated adjustment hole is provided between the first support bar 231 and the limiting support bar 233; the first support bar 231 and the limiting support bar 233 are locked by screws passing through the elongated adjustment hole, and the height of the limiting support bar 233 in the Z direction can be adjusted. If an elongated adjustment hole can be provided at the lower end of the first support bar 231 and a regular screw hole can be provided at the limit support bar 233, the installation position of the limit support bar 233 at the lower end of the first support bar 231 can be adjusted, and the distance between the limit support bar 233 and the surface of the storage area 101 can be further adjusted. For example, an elongated adjustment hole can be provided at the upper end of the limiting support bar 233, and a normal screw hole can be provided at the first support bar 231. This allows adjustment of the installation position of the limiting support bar 233 at the lower end of the first support bar 231, and further adjustment of the distance between the limiting support bar 233 and the surface of the storage area 101.

[0035] Furthermore, the distance between the limiting support bar 233 and the surface of the storage area 101 is A, and the thickness of the plate to be transferred is B, where 2B > A > B; Specifically, the distance between the limiting support bar 233 and the surface of the storage area 101 is set to 2B > A > B, which effectively blocks the plates and prevents the bottom plate from being sent out along the Y direction. This prevents the plate being sent out from being carried out along with the plate above it due to friction, thus preventing more than two plates from being mistakenly sent to the processing area 102.

[0036] In one embodiment, the upper ends of the first support bar 231 and the second support bar 232 are inclined in opposite directions, so that the top of the hopper 201 forms a funnel-shaped feed inlet, making feeding more convenient.

[0037] In one embodiment, a plurality of guide bars 110 are arranged in the storage area 101 to form a platform for the storage area 101, and the guide bars 110 are arranged along the Y direction. The board is supported on the platform composed of the guide bars 110; a guide groove 120 is formed between adjacent guide bars 110; the friction during the transportation of the board is reduced to a certain extent, and the guide groove 120 is a hollow groove.

[0038] In one embodiment, the processing area 102 is provided with a first stop bar 130 and a second stop bar 140, which are arranged along the Y direction and form a processing position between them. Specifically, the first stop bar 130 and the second stop bar 140 can be metal strips or wooden strips. The first stop bar 130 and the second stop bar 140 are arranged parallel to each other.

[0039] The first stop bar 130 is equipped with a spring piece 131, and the second stop bar 140 is fixedly installed; the sheet metal is pushed into the processing position by the feeding mechanism 300, and the spring piece 131 provides elastic force to push the sheet metal towards the second stop bar 140; specifically, as shown... Figure 1 and Figure 4 As shown, the first baffle 130 has a plurality of grooves 132 on its side near the storage area 101. A spring piece 131 is installed in the groove 132. The spring piece 131 includes a mounting part 1311 and an elastic part 1312. The mounting part 1311 is fixed in the groove 132 with a screw. The elastic part 1312 extends out of the groove 132 and extends in an arc shape away from the storage area 101. The elastic part 1312 is arc-shaped and a bending hook 1313 is provided at the end of the elastic part 1312.

[0040] The above structure allows the processing station to accommodate boards of a certain size, and all boards within a certain size can be positioned after being placed.

[0041] like Figure 1 As shown, when the sheet material is pushed along the Y direction by the feeding mechanism 300 and enters the processing position, due to the arc-shaped setting of the elastic part 1312, the sheet material enters the processing position and better pushes the elastic part 1312 to deform. The elastic force of the elastic part 1312 pushes the sheet material towards the second stop bar 140, so that the sheet material is close to the second stop bar 140 to achieve positioning. Here, the distance between the first stop bar 130 and the second stop bar 140 is defined as D. This is applicable to plates with a width equal to or slightly less than D, ensuring that the plate can be pressed against the second stop bar 140 by the elastic force of the elastic part 1312 after entering the processing position.

[0042] Optionally, such as Figure 1 As shown, this device is also equipped with a vacuum pump 400. The vacuum pump 400 acts on the processing position to adsorb the board onto the table surface, preventing the board from changing position during processing. After the board is processed, the vacuum pump 400 stops working.

[0043] In one implementation, such as Figure 10-11 As shown, the feeding mechanism 300 includes: a bracket 310, a pusher 320 mounted on the bracket 310, a motor 330 and a cylinder 340 mounted on the bracket 310; the bracket 310 is a metal square tube extending along the X direction, and in the X direction, the length of the bracket 310 is slightly less than the length of the platform 100; the bracket 310 is provided with a first track 311 in the Z direction, and the pusher 320 is mounted on the first track 311 by a slider; the output shaft of the cylinder 340 is connected to the pusher 320 and pushes the pusher 320 to move in the Z direction; Platform 100 is provided with rack 150 and second track 160, which are arranged along the Y direction; bracket 310 is mounted on second track 160 by slider; output shaft of motor 330 is provided with gear, which meshes with rack 150. When motor 330 runs, the entire feeding mechanism 300 moves along the Y direction through the cooperation of gear and rack 150. Furthermore, the pusher 320 includes: a fixed plate 321 and multiple sheet metal strips 322; the sheet metal strips 322 are bent into an L-shape; when the pusher 320 moves upward, the sheet metal strips 322 pass through the guide groove 120 and protrude upward; multiple sheet metal strips 322 are distributed along the X direction to simultaneously push the plates of the six material bins 201.

[0044] like Figure 5 As shown, a sheet metal strip 322 is provided for each guide groove 120, such as... Figure 12As shown, in order to enable multiple sheet metal strips 322 to move upward or downward simultaneously and stably, the feeding mechanism 300 is equipped with multiple cylinders 340.

[0045] The thickness of the sheet metal to be transferred is defined as B. The height of the sheet metal strip 322 protruding upward from the tabletop of storage area 101 is less than B, so that the sheet metal strip 322 can only push one sheet metal at a time. like Figure 1 As shown, during use, the cylinder 340 drives the pusher 320 to move upward along the first track 311, and the sheet metal strip 322 passes through the guide groove 120 and protrudes upward; the motor 330 runs through the cooperation of gears and racks 150, so that the entire feeding mechanism 300 moves along the Y direction, pushes the sheet metal out from the bottom of the hopper 201, and moves the sheet metal from the storage area 101 into the processing area 102; After the sheet material enters the processing position, the spring 131 of the first stop bar 130 pushes the sheet material to the second stop bar 140. At the same time, the vacuum pump 400 works to adsorb the sheet material at the processing position, effectively positioning the sheet material and preventing the sheet material from changing position during processing. The cylinder 340 drives the pusher 320 to move down along the first track 311. The motor 330 runs and, through the cooperation of the gear and rack 150, causes the entire feeding mechanism 300 to move in the reverse direction and reset, waiting to move the next sheet material. In this embodiment, the processing area 102 is equipped with a drilling mechanism to process the sheet metal. After processing, the vacuum pump 400 stops working, and the table loses its suction function. The feeding mechanism 300 repeats the previous feeding action. When a new sheet metal is fed into the processing position, it pushes the finished sheet metal forward to replace its position. The finished sheet metal pushed out of the processing position can be collected by workers, or the processing area 102 can be connected to a conveyor belt, so that the next sheet metal pushes the previous sheet metal into the conveyor belt.
